Notis

Check unfamiliar login IPs from Slack

Post a login IP in Slack and let Notis check its proxy, VPN, or Tor status with Ip2proxy.

Trigger

Channel Message Received

Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.

Action

Check Proxy Status of an IP

Tool to check if an IP address is a proxy. Use after obtaining an IP to detect proxy, VPN, or Tor status.

Why this helps

Security questions can get buried while you switch between Slack and a separate IP lookup tool.

  • Get an IP classification without leaving the conversation.
  • Make the first check part of the team's existing security discussion.
  • Reduce manual lookups during an unexpected login review.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Ip2proxy to Notis once in the portal.
  • 2Create an automation in the portal or ask Notis for one in plain language.
  • 3Tell Notis to check an IP posted in Slack and report whether it is a proxy, VPN, or Tor.
  • 4Choose the Slack channel message trigger and a channel for run reports, then test with a real login IP.

Questions about this workflow

Does this check every Slack message?

The selected Slack channel message trigger starts the automation when a channel message arrives. The prompt can ask Notis to check an IP when one is present.

What does Ip2proxy return?

The Ip2proxy action checks an IP address for proxy status, including VPN or Tor classification.
